Saved my life. A self-tapping screw was accidentally sucked in, it got stuck in the air separator and broke it. If you have a Rainbow vacuum, you know how awful it is without it. Well I thought my machine was dead. My husband figured out that part is all we need to get it working again and the rest is history. Sooooo glad I checked out Revain "if they have it"! It would have cost me a service charge and I don't know what the dealer has for this part. The happy vacuum cleaner is here!
